Manchester United's David De Gea leaves match vs. Arsenal with undisclosed injury

Goodbye forever?

Manchester United goalkeeper David De Gea left Sunday's match against Arsenal in the second half, trudging off the Old Trafford pitch - for what could be the last time - with an undisclosed ailment.

If rampant speculation about the Spaniard's future is to be believed, this is the final time United supporters will see the goalkeeper put his skills on display inside the Theatre of Dreams.

Unless, of course, he returns as a member of Real Madrid, which is the club consistently linked with a summer move for the 24-year-old.
